Aeon Sphere Grid

The Aeon Sphere Grid is a supplemental area for increasing abilities and character attributes for your Aeons during the Final Fantasy X Collaboration Event regions. It is first accessed during Dream Within a Dream, Part 3 and builds up as you progress through the rest of the Dream Within a Dream storyline.

The space is an analogue of the character development system used in Final Fantasy X. Here, attributes are directly applied as extra bonuses to either a specific Aeon, or as a general Aeon enhancement. These are applied while you have a relevant Aeon summoned, replacing what would normally be your sub-job.

Controls
You can access this space from the Dream Within a Dream, Episode 3, Episode 4, and Conclusion regions by tapping on the blue and gold icon near the top corner of the map screen.

When you're finished clearing and activating spaces, you can return to your story region or go to the Sphere Grid by clicking the purple icon in the top corner of the map screen.
